A/c Unit Assembly

Removal & Installation

Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of electric shock, electric leakage, or similar accidents if the high voltage component and Nissan Ariya vehicle are handled incorrectly. Be sure to follow the correct work procedures when performing inspection and maintenance.

WARNING:

• Be sure to remove the service plug in order to disconnect the high voltage circuits before performing inspection or maintenance of high voltage system harnesses and parts.

• The removed service plug must always be carried in a pocket of the responsible worker or placed in the tool box during the procedure to prevent the plug from being connected by mistake.

• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses before beginning work on the high voltage system.

• Never allow workers other than the responsible person to touch the Nissan Ariya vehicle containing high voltage parts. To keep others from touching the high voltage parts, these parts must be covered with an insulating sheet except when using them.

• Refer to Precautions for High Voltage.

CAUTION:

• Never bring the vehicle into the READY status with the service plug removed unless otherwise instructed in the Service Manual. A malfunction may occur if this is not observed.

• Perform lubricant return operation before each refrigeration system disassembly. However, if a large amount of refrigerant or lubricant is detected, never perform lubricant return operation. Refer to Perform Lubricant Return Operation.

REMOVAL

Follow the instructions below before starting the procedure.

CAUTION:

• Disconnect high voltage circuit. Refer to HOW TO DISCONNECT HIGH VOLTAGE : Precautions.

• Check voltage in high voltage circuit. Refer to CHECK VOLTAGE IN HIGH VOLTAGE CIRCUIT : Precautions.

Use a refrigerant collecting equipment (for HFO-1234yf) to discharge the refrigerant. Refer to Recycle Refrigerant.

Remove A/C unit assembly cover. Refer to Removal & Installation.

Remove A/C unit assembly mounting nuts, and then remove A/C unit assembly from Nissan Ariya vehicle.

INSTALLATION

Note the following items, and then install in the reverse order of removal.

CAUTION:

• For the A/C unit assembly mounting nuts, tighten the nuts in the order of 1→2 in the figure, and then tighten the other nuts.

  

• Use a refrigerant collecting equipment (for HFO-1234yf) to charge the refrigerant. Refer to Charge Refrigerant.
